Aurora is the result of the interaction between precipitating energetic electrons and protons
with the upper atmosphere. Viewed from space, it generally occurs in continuous and diffuse …

Optical structures located equatorward of the main auroral oval often exhibit different
morphologies and dynamics than structures at higher latitudes. In some cases, questions …

Over the first 2.5 years of operation, the FUV instrument on the IMAGE spacecraft observed
more than 2400 substorm onsets in the Northern Hemisphere. The observations confirm …

The Far Ultraviolet Imager (FUV) on board the IMAGE satellite provides an instantaneous
global view of the OI 135.6‐nm nightglow with 2 min time resolution. Because the OI 135.6 …

Thermospheric O/N2 column density ratios referenced at a N2 column density of 1017 cm− 2
are obtained using the IMAGE SI‐13 and TIMED/GUVI far‐ultraviolet (FUV) dayglow data …

The article presents a review of scientific problems and methods of ultraviolet astronomy,
focusing on perspective scientific problems (directions) whose solution requires UV space …

It is commonly assumed that the aurora borealis (Northern Hemisphere) and aurora australis
(Southern Hemisphere) are mirror images of each other because the charged particles …

An accurate description of the state of the ionosphere is crucial for understanding the
physics of Earth's coupling to space, including many potentially hazardous space weather …

Abstract The NASA Ionospheric Connection Explorer (ICON) was launched in October 2019
and has been observing the upper atmosphere and ionosphere to understand the sources …

Based on simultaneous imaging data from IMAGE FUV and Polar VIS Earth camera and
DMSP particle measurements we report two events where a theta aurora was observed in …
